In the AppleTalk subsystem in the Linux kernel before 5.1, there is a
potential NULL pointer dereference because register_snap_client may return
NULL. This will lead to denial of service in net/appletalk/aarp.c and
net/appletalk/ddp.c, as demonstrated by unregister_snap_client, aka
CID-9804501fa122.
